Growth and Properties of Zn1−x Cd x O and Zn1−x Cd x O/ZnO Core/shell Nanoparticles
Abstract:Octylamine capped Zn1−x Cd x O alloys and Zn1−x Cd x O/ZnO core/shell nanoparticles have been grown by the thermal decomposing of zinc and cadmium cupferronates in organic solvents. Zn1−x Cd x O alloys incorprated with different concentration of Cd have been grown by quickly injecting of their precursors at 200 °C. Zn1−x Cd x O/ZnO core/shell nanoparticles are performed by slowly injecting of shell precursors at 180 °C. The prepared nanoparticles are characterized by X-ray diffraction, absorption spectrometer, Mirco-Raman spectrometer and transmission electron microscopy. The band gap of ZnCdO alloys shrinks linearly and the crystal lattice expands with an increase of Cd concentration. The growth of ZnO shells on ZnCdO cores enhances the core luminescence dramatically and results in a red shift in the absorption and emission of Zn1−x Cd x O cores.
